Granular components are predominantly found within the nucleolus of eukaryotic cells. The nucleolus is a non-membrane-bound structure within the nucleus, primarily involved in the synthesis and assembly of ribosomal RNA (rRNA). The granular component of the nucleolus consists of ribonucleoprotein particles and is one of three main sections, the others being the fibrillar center and the dense fibrillar component.
In the cytoplasm, granular components can include lysosomes, secretory granules, and zymogen granules. These structures are involved in various cellular processes such as digestion, secretion, and storage of enzymes.
